Due to time constraints, I wasn't able to get replacements for the 2 (expensive) lumps of very grotty foam that are around the injectors, the one below the pipes was in bits, and not reusable, the larger upper one is back on, albeit with some bits missing. In all honesty, I can't tell a significant difference in the noise from the engine, so are these lumps of foam worth replacing at some stage, or is there another reason for having them there that's not noise related?

Shore, if it was easy, everybody would be doin it.😁
